                         performed in Brazil. Three coronal processes are discussed: (1) 
                         coronal heating by surface Alfven waves, (2) coronal heating by 
                         global Alfven waves, and (3) generation of type III radio 
                         emission. The surface Alfven waves can power, directly, at least 
                         10 of the required coronal flux density; in the case of mode 
                         conversion into kinetic Alfven waves the bulk of energy flux 
                         density can be provided. The global waves can power at least 20 of 
                         the required coronal energy flux density. It is shown that the 
                         electromagnetic oscillating two-stream instability driven by 
                         intense Langmuir waves, can be a likely generation mechanism of 
                         type-III radio bursts.",
